Technical Field
The present disclosure relates to hinges, and particularly to a sliding hinge for a dual-screen electronic device.
Background
The electronic devices such as tablet computers and notebook computers have developed a dual-screen design, which meets the current trend of displaying images in large size. The double screens are mutually connected through hinges and are suitable for being relatively unfolded or folded and switched into use states of different situations. For example, in the unfolded state, the images can be synchronously output through the double screens, so that the display range of the images is increased. In the folded state, the two screens are stacked up and down to reduce the area size of the portable electronic device, which is beneficial for a user to carry or store in a backpack by hand.
However, the conventional dual-screen electronic device using the hinge has a large space in the unfolded state, which results in poor viewing effect of the output image, and a portion of the hinge is located in the space between the dual screens, so that the unfolded electronic device is not beautiful in appearance. Therefore, it is an important development goal to develop a hinge to overcome the disadvantages of the electronic device, such as the large distance between the two screens and the unattractive appearance.
In order to solve the problem that the distance between two screens is too large in a double-screen machine, the design of the scheme is that the distance between the two screens is reduced through the design of the machine body and the screens which can slide relatively, so that a better watching effect is achieved.
Disclosure of Invention
The invention provides a sliding type hinge which is suitable for a double-screen electronic device, has a sliding effect, and can reduce the distance between double screens of the electronic device in an unfolding state so as to be adjacent to each other, thereby obtaining a better display effect and improving the attractiveness in the unfolding state.
The sliding hinge comprises a torsion module, two brackets, a carrier plate, a driving gear set and a sliding bracket. The torsion module is provided with a first rotating shaft and a second rotating shaft, and is suitable for rotating in opposite directions and generating torsion. The two brackets are respectively arranged on the first rotating shaft and the second rotating shaft. The carrier plate is arranged on one of the brackets. The driving gear set is disposed on the carrier and coupled to the first shaft. The sliding bracket is coupled to the driving gear set and movably arranged on a top surface of the carrier plate. The two supports are suitable for rotating relative to the torsion module through the first rotating shaft and the second rotating shaft, so that the two supports are mutually overlapped or mutually unfolded, and meanwhile, the gear set is driven to drive the sliding support to slide along the support plate. When the two brackets are mutually overlapped, the sliding bracket is relatively far away from the first rotating shaft. When the two brackets are unfolded mutually, the sliding bracket is relatively close to the first rotating shaft.
The electronic device of the invention comprises a first body, a second body and a sliding hinge. The first body comprises a first shell and a first screen, and the first screen is fixedly arranged on the first shell. The second body comprises a second shell and a second screen, and the second screen is movably arranged on the second shell. The sliding hinge is configured between the first body and the second body and comprises a torsion module, two supports, a support plate, a drive gear set and a sliding support. The torsion module is provided with a first rotating shaft and a second rotating shaft, and is suitable for rotating in opposite directions and generating torsion. The two brackets are respectively arranged on the first rotating shaft and the second rotating shaft and are respectively connected with the first shell and the second shell. The carrier plate is arranged on one of the brackets and is positioned in the first shell. The driving gear set is disposed on the carrier and coupled to the first rotating shaft. The sliding bracket is coupled to the driving gear set and movably arranged on a top surface of the carrier plate. The second screen is connected with the sliding support. The two supports are suitable for the rotation of the torque force module relative to the first rotating shaft and the second rotating shaft, so that the first machine body and the second machine body are mutually overlapped or mutually unfolded, meanwhile, the gear set is driven to drive the sliding support to slide along the support plate, when the first machine body and the second machine body are mutually overlapped, the sliding support is relatively far away from the first rotating shaft, when the first machine body and the second machine body are mutually unfolded to 180 degrees, the sliding support is relatively close to the first rotating shaft, and the first screen is driven to move towards the second screen and is mutually adjacent to the second screen, so that the torque force module is shielded.
In view of the above, the sliding hinge of the present invention utilizes the driving gear set to couple to the sliding bracket, when the two brackets rotate with the first rotating shaft and the second rotating shaft in opposite directions and generate a torque, the driving gear set starts to rotate through the rotation of the first rotating shaft to drive the sliding bracket to slide along the carrier plate, and when the two brackets are overlapped with each other, the sliding bracket is relatively far away from the first rotating shaft. When the two brackets are unfolded mutually, the sliding bracket is relatively close to the first rotating shaft. Therefore, in the process of unfolding and closing the sliding hinge, the sliding support can be synchronously driven to the relative position of the support plate through the driving gear set.
Further, the sliding hinge of the present invention is suitable for connecting a first screen and a second screen of an electronic device. The first body and the second body can rotate relative to the torque module to be mutually overlapped or mutually unfolded. When the first machine body and the second machine body are mutually overlapped, the sliding support is relatively far away from the first rotating shaft. When the first body and the second body are unfolded to 180 degrees, the sliding support is relatively close to the first rotating shaft, so that the first screen is driven to move towards the second screen and stretch over the first body and the second body, and the first screen and the second screen are close to each other to shield the torsion module. Thereby achieving better image display effect and improving the aesthetic degree of the electronic device.
